Abstract

A producing method of a base member provided with a printed layer, the method including: disposing a printing plate including a screen plate having an opening pattern and a frame body supporting the screen plate so that the printing plate is opposed to a printing target surface of the base member having at least one bent portion; disposing a squeegee so as to be opposed to a plate surface of the screen plate opposite to the base member; and forming the printed layer by extruding a printing material onto the printing target surface by the squeegee via the opening pattern of the screen plate in a state where the frame body is supported so as to be relatively movable with respect to the printing target surface in a normal direction of the printing target surface.

First claim

The invention claimed is:

1. A base member provided with a printed layer, comprising: a printing target surface having at least one bent portion; and the printed layer formed on the bent portion of the printing target surface, wherein the bent portion has a twisted structure, wherein a distribution of a thickness of the printed layer is within 20% with respect to an average thickness of the printed layer, and wherein the twisted structure comprising a radius of curvature R 1 on one side and a radius of curvature R 2 on an opposite side such that the radius of curvature R 2 is smaller than the radius of curvature R 2 and differ by at least 5%.

2. The base member provided with the printed layer according to claim 1 , wherein the twisted structure is a structure wherein an intersection angle between an imaginary line connecting the starting points of the bent portion and one side of an end surface of the base member satisfies 0.degree.<<90.degree.

3. A base member provided with a printed layer, comprising: a printing target surface having at least one bent portion; and the printed layer formed on the bent portion of the printing target surface, wherein the bent portion has a curved surface having two or more different radii of curvature,
wherein a distribution of a thickness of the printed layer is within 20% with respect to an average thickness of the printed layer, and wherein the twisted structure comprising a radius of curvature R 1 on one side and a radius of curvature R 2 on an opposite side such that the radius of curvature R 2 is smaller than the radius of curvature R 2 and differ by at least 5%.

4. The base member provided with the printed layer according to claim 1 , wherein at least one of the bent portion is a recessed curved shape wherein the printing target surface is dented.

5. The base member provided with the printed layer according to claim 1 , further comprising a protruded curved shape which is convex to the printing target surface.

6. The base member provided with the printed layer according to claim 1 , further comprising a flat portion, wherein an optical density of the printed layer is 4 or more in both of the flat portion and the bent portion.

7. The base member provided with the printed layer according to claim 1 , wherein a bending depth of the bent portion is 3 mm or more.

8. The base member provided with the printed layer according to claim 1 , wherein a radius of curvature of the bent portion is 4,000 mm or less.
